Pls help. Determining if slopes are parallel, perpendicular, or neither.

Mathematics
1 answer:
Naily [24]3 years ago
4 0

Answer:

Line p is parallel

Line n is perpendicular

Lines m and q are neither

Step-by-step explanation:

Parallel lines have the same slopes

Perpendicular lines have opposite reciprocal slopes (Switch sign <u>AND</u> flip numerator and denominator)

Any other slopes would be "neither"

Answer:

The simplified expression is:

\frac{3^9y}{2\times \:81}=\frac{243y}{2}

Step-by-step explanation:

Given the expression

\frac{3^9\times \:y}{2\times 81}

solving the expression

\frac{3^9\times \:y}{2\times 81}=\frac{3^9y}{162}

        =\frac{3^9y}{3^4\times \:2}                ∵    162=3^4\times \:2      

        =\frac{3^5y}{2}                   ∵   \mathrm{Apply\:exponent\:rule}:\quad \frac{x^a}{x^b}=x^{a-b}

       =\frac{243y}{2}                  ∵    3^5=243

Therefore, the simplified expression is:

\frac{3^9y}{2\times \:81}=\frac{243y}{2}

Automobile tires can have a symmetric tread or an asymmetric tread. An experiment is to be conducted to determine whether the st
Genrish500 [490]

Answer:

Hello your question lacks the required options here are the options

By blocking on stopping distance

By blocking on tire tread type

By blocking on automobile type

By blocking on automobile size

Without blocking

Answer : By blocking on automobile size

Step-by-step explanation:

The experiment can best be conducted by blocking on the automobile and this is because the Automobile size and the stopping distance are proportionally related (associated ) as seen from the previous experiments hence the best experiment is By blocking on the size of the automobile is very crucial .

we can have a symmetric tread tire or an asymmetric tires fixed on the different types of Automobiles simultaneously and see if the stopping  distance will be affected when we change the tires that way we are blocking on the Automobile size the same type of tires will be fixed at the same time on each automobile size

Quadratic equations and complex numbers PLEASE HELPPPP ASAP
kondor19780726 [428]

we are given

27x^3-1=0

we can also write it as

(3x)^3-(1)^3=0

now, we can use factor formula

a^3-b^3=(a-b)(a^2+ab+b^2)

we can use above formula

we get  

(3x)^3-(1)^3=(3x-1)((3x)^2+3x\times 1+(1)^2)

now, we can simplify it

27x^3-1=(3x-1)(9x^2+3x+1)

now, we can set it to 0

27x^3-1=(3x-1)(9x^2+3x+1)=0

and then we can solve for x

(3x-1)(9x^2+3x+1)=0

3x-1=0

x=\frac{1}{3}

9x^2+3x+1=0

now, we can use quadratic formula

x=\frac{-b\pm \sqrt{b^2-4ac}}{2a}

now, we can plug values

and we get

x=\frac{-3\pm \sqrt{3^2-4\cdot \:9\cdot \:1}}{2\cdot \:9}

x=-\frac{1}{6}+i\frac{\sqrt{3}}{6},\:x=-\frac{1}{6}-i\frac{\sqrt{3}}{6}

So, we will get solution as

x=\frac{1}{3},\:x=-\frac{1}{6}+i\frac{\sqrt{3}}{6},\:x=-\frac{1}{6}-i\frac{\sqrt{3}}{6}...............Answer
